    • Senior Hydrogeologist
      • Mar 2016 - Present

      I have recently founded an environmental and engineering consulting firm with the goal of expanding and leveraging the technical and leadership skills that I have acquired over the past two decades. 212 Environmental Consulting, LLC will be focused on the design and implementation of corrective measures at complex sites underlain with petroleum, chlorinated, and emerging contaminant releases. This new venture will have unique expertise in the innovative assessment and mitigation of the vapor intrusion pathway, as well as human health risk assessment, sustainable remediation, and quantifying natural source zone depletion rates.

  • Trihydro Corporation
    • United States
    • Environmental Services
    • 300 - 400 Employee
    • Team Leader
      • Jan 2009 - Mar 2016

      Team Leader overseeing operations in three offices in the Midwest including Cincinnati, Ohio; St. Louis, Missouri; and Chicago, Illinois. I was responsible for more than $4 million in net revenue working with a diverse team of more than 20 professionals. I assisted with fiscal planning, business development, and growth within these regional offices. In addition, I managed a diverse group of professionals with specialties including human health and ecological risk assessment, vapor intrusion, monitored natural attenuation, and remedial systems design and implementation. I was a technical advisor and program manager on a number of multifaceted projects across the United States. Finally, I acted as a technical resource both internally and externally for issues related to vapor intrusion, LNAPL mobility, and source zone natural depletion. This includes collaboration with industry and academia on multiple research projects. Major accomplishments included completion of groundwater corrective measures study, design, and implementation at a former refinery in Ohio. LNAPL was present across a several hundred-acre smear zone extending beyond the refinery into residential and commercial areas. The final remedy, as negotiated with the regulatory agency, included short term engineered recovery when hydraulic conditions were favorable followed by long term management of residual LNAPL via natural attenuation. Source zone depletion rates were compared against LNAPL recovery achieved via active remedial systems as one of multiple lines of evidence to determine when engineered recovery endpoints have been achieved. A dynamic multimedia monitoring program was established for tracking progress towards agreed upon final remedy goals. Show less

    • Project Manager/Hydrogeologist
      • Jun 2002 - Jan 2009

      I served as a Project Manager for numerous projects involving site assessment and remediation including leaking underground storage tank sites, municipal landfills, solvent recycling facilities, and refineries. As part of my responsibilities, I engaged in marketing and business development including growth of more than $300K annually in net revenue associated with managing environmental liability at municipal and community landfills across the State of Wyoming. Major accomplishments included completion of a vapor intrusion evaluation in a residential community located adjacent to a former refinery in the Midwest. Vapor intrusion investigation, remediation, and routine monitoring activities have continued on this site for more than a decade. I oversaw all aspects of this project including assessment, remediation, coordination with key stakeholders and multiple regulatory agencies. I assisted internal and external legal teams in realizing cost avoidances totaling millions of dollars for unnecessary mitigation within more than 60 residences and dismissal of three class action lawsuits in the United States Fifth Circuit Court of Appeals.

    • Project Geologist
      • Sep 2000 - Jun 2002

      I functioned as a Project Geologist tasked with leading subsurface investigations, vapor intrusion assessments, feasibility studies, and remedy implementation at a former Air Force Base in Denver, Colorado and Chemical Depot in Pueblo, Colorado. Major accomplishments included the execution of a vapor intrusion assessment that involved collection and analysis of indoor air, outdoor air, crawlspace air, sub-slab soil vapor, and near slab soil vapor samples over six quarters within a residential community located adjacent to the former Air Force Base. I oversaw sample collection, validation, statistical analyses, and graphical presentation of the monitoring results. I also assisted with pathway evaluation, human health risk assessment, numerical modeling, mitigation system design, installation, and long-term operations and maintenance. Show less

  • Thermoretec Corporation
    • Austin, Texas Area
    • Staff Geologist
      • Jun 1998 - Jun 2000

      I acted as a Staff Geologist responsible for subsurface assessment, routine monitoring, remedial system maintenance, as well as routine and non-routine reporting for former and active gas processing plants, refineries, industrial facilities, and railroad sites. Major accomplishments included completion of decommissioning, assessment, remedial design, construction, and implementation at two former gas-processing plants. These investigations entailed preparing work plans in cooperation with regulatory agencies, completing cost estimates and bid documents, coordinating subcontractors and laboratories, supervising field activities, interpreting laboratory and field data, and preparing reports for client and regulatory review. Site responsibilities included multimedia sampling, fingerprinting LNAPL samples, determining sources of comingled plumes, characterizing and disposing of hazardous waste, supervising subcontractors and field crews, interpreting hydrogeologic and analytical data, validating laboratory results, and report writing. One phase of these projects included measuring LNAPL transmissivity in a number of wells to evaluate the effectiveness of active and passive hydrocarbon recovery technologies. Show less
